This function is also used in other builtins than stripspace, so it makes sense to have it in a more generic place. Since it operates on an strbuf and the function is declared in strbuf.h, move it to strbuf.c and add the corresponding prefix to its name, just like other API functions in the strbuf_* family. Also switch all current users of stripspace() to the new function name and keep a temporary wrapper inline function for any topic branches still using stripspace().

Remove a cache invalidation which would cause the shared index to be rewritten on as-is commits. When the cache-tree has changed, we need to update it. But we don't necessarily need to update the shared index. So setting active_cache_changed to SOMETHING_CHANGED is unnecessary. Instead, we let update_main_cache_tree just update the CACHE_TREE_CHANGED bit. In order to test this, make test-dump-split-index not segfault on missing replace_bitmap/delete_bitmap. This new codepath is not called now that the test passes, but is necessary to avoid a segfault when the new test is run with the old builtin/commit.c code.

One of the most common uses of git_path() is to pass a constant, like git_path("MERGE_MSG"). This has two drawbacks: 1. The return value is a static buffer, and the lifetime is dependent on other calls to git_path, etc. 2. There's no compile-time checking of the pathname. This is OK for a one-off (after all, we have to spell it correctly at least once), but many of these constant strings appear throughout the code. This patch introduces a series of functions to "memoize" these strings, which are essentially globals for the lifetime of the program. We compute the value once, take ownership of the buffer, and return the cached value for subsequent calls. cache.h provides a helper macro for defining these functions as one-liners, and defines a few common ones for global use. Using a macro is a little bit gross, but it does nicely document the purpose of the functions. If we need to touch them all later (e.g., because we learned how to change the git_dir variable at runtime, and need to invalidate all of the stored values), it will be much easier to have the complete list. Note that the shared-global functions have separate, manual declarations. We could do something clever with the macros (e.g., expand it to a declaration in some places, and a declaration _and_ a definition in path.c). But there aren't that many, and it's probably better to stay away from too-magical macros. Likewise, if we abandon the C preprocessor in favor of generating these with a script, we could get much fancier. E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz". But the small amount of saved typing is probably not worth the resulting confusion to readers who want to grep for the function's definition.

In preparation for adding date modes that may carry extra information beyond the mode itself, this patch converts the date_mode enum into a struct. Most of the conversion is fairly straightforward; we pass the struct as a pointer and dereference the type field where necessary. Locations that declare a date_mode can use a "{}" constructor. However, the tricky case is where we use the enum labels as constants, like: show_date(t, tz, DATE_NORMAL); Ideally we could say: show_date(t, tz, &{ DATE_NORMAL }); but of course C does not allow that. Likewise, we cannot cast the constant to a struct, because we need to pass an actual address. Our options are basically: 1. Manually add a "struct date_mode d = { DATE_NORMAL }" definition to each caller, and pass "&d". This makes the callers uglier, because they sometimes do not even have their own scope (e.g., they are inside a switch statement). 2. Provide a pre-made global "date_normal" struct that can be passed by address. We'd also need "date_rfc2822", "date_iso8601", and so forth. But at least the ugliness is defined in one place. 3. Provide a wrapper that generates the correct struct on the fly. The big downside is that we end up pointing to a single global, which makes our wrapper non-reentrant. But show_date is already not reentrant, so it does not matter. This patch implements 3, along with a minor macro to keep the size of the callers sane.

To figure out the author ident for a commit, we call determine_author_info(). This function collects information from the environment, other commits (in the case of "--amend" or "-c/-C"), and the "--author" option. It then uses fmt_ident to generate the final ident string that goes into the commit object. fmt_ident is therefore responsible for any quality or validation checks on what is allowed to go into a commit. Before returning, though, we call split_ident_line on the result, and feed the individual components to hooks via the GIT_AUTHOR_* variables. Furthermore, we do extra validation by feeding the split to sane_ident_split(), which is pickier than fmt_ident (in particular, it will complain about an empty email field). If this parsing or validation fails, we skip updating the environment variables. This is bad, because it means that hooks may silently see a different ident than what we are putting into the commit. We should drop the extra sane_ident_split checks entirely, and take whatever fmt_ident has fed us (and what will go into the commit object). If parsing fails, we should actually abort here rather than continuing (and feeding the hooks bogus data). However, split_ident_line should never fail here. The ident was just generated by fmt_ident, so we know that it's sane. We can use assert_split_ident to double-check this. Note that we also teach that assertion to check that we found a date (it always should, but until now, no caller cared whether we found a date or not). Checking the return value of sane_ident_split is enough to ensure we have the name/email pointers set, and checking date_begin is enough to know that all of the date/tz variables are set.

When we generate the commit-message template, we try to report an author or committer ident that will be of interest to the user: an author that does not match the committer, or a committer that was auto-configured. When doing so, if we encounter what we consider to be a bogus ident, we immediately die. This is a bad idea, because our use of the idents here is purely informational. Any ident rules should be enforced elsewhere, because commits that do not invoke the editor will not even hit this code path (e.g., "git commit -mfoo" would work, but "git commit" would not). So at best, we are redundant with other checks, and at worse, we actively prevent commits that should otherwise be allowed. We should therefore do the minimal parsing we can to get a value and not do any validation (i.e., drop the call to sane_ident_split()). In theory we could notice when even our minimal parsing fails to work, and do the sane thing for each check (e.g., if we have an author but can't parse the committer, assume they are different and print the author). But we can actually simplify this even further. We know that the author and committer strings we are parsing have been generated by us earlier in the program, and therefore they must be parseable. We could just call split_ident_line without even checking its return value, knowing that it will put _something_ in the name/mail fields. Of course, to protect ourselves against future changes to the code, it makes sense to turn this into an assert, so we are not surprised if our assumption fails.

Just like other hints such as "Changes to be committed" we show in the editor to remind the committer what paths were involved in the resulting commit to help improving their log message, this section is merely a reminder. Traditionally, it was not made into comments primarily because it has to be generated outside the wt-status infrastructure, and also because it was meant as a bit stronger reminder than the others (i.e. explaining how you resolved conflicts is much more important than mentioning what you did to every paths involved in the commit). But that still does not make this hint a part of the log message proper, and not showing it as a comment is inviting mistakes. Note that we still notice "Conflicts:" followed by list of indented pathnames as an old-style cruft and insert a new Signed-off-by: before it. This is so that "commit --amend -s" adds the new S-o-b at the right place when used on an older commit. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Extract a helper function from prepare_to_commit() to determine where to place a new Signed-off-by: line, which is essentially the true "end" of the log message, ignoring the trailing "Conflicts:" line and everything below it. The detection _should_ make sure the "Conflicts:" line it finds is truly the conflict hint block by checking everything that follows is a HT indented pathname to avoid false positive, but this logic will be revamped in a later patch to ignore comments and blanks anyway, so it is left as-is in this step.

Originally the color-parsing function was used only for config variables. It made sense to pass the variable name so that the die() message could be something like: $ git -c color.branch.plain=bogus branch fatal: bad color value 'bogus' for variable 'color.branch.plain' These days we call it in other contexts, and the resulting error messages are a little confusing: $ git log --pretty='%C(bogus)' fatal: bad color value 'bogus' for variable '--pretty format' $ git config --get-color foo.bar bogus fatal: bad color value 'bogus' for variable 'command line' This patch teaches color_parse to complain only about the value, and then return an error code. Config callers can then propagate that up to the config parser, which mentions the variable name. Other callers can provide a custom message. After this patch these three cases now look like: $ git -c color.branch.plain=bogus branch error: invalid color value: bogus fatal: unable to parse 'color.branch.plain' from command-line config $ git log --pretty='%C(bogus)' error: invalid color value: bogus fatal: unable to parse --pretty format $ git config --get-color foo.bar bogus error: invalid color value: bogus fatal: unable to parse default color value Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Many config-parsing helpers, like parse_branch_color_slot, take the name of a config variable and an offset to the "slot" name (e.g., "color.branch.plain" is passed along with "13" to effectively pass "plain"). This is leftover from the time that these functions would die() on error, and would want the full variable name for error reporting. These days they do not use the full variable name at all. Passing a single pointer to the slot name is more natural, and lets us more easily adjust the callers to use skip_prefix to avoid manually writing offset numbers. This is effectively a continuation of 9e1a5ebe, which did the same for parse_diff_color_slot. This patch covers all of the remaining similar constructs.

When figuring out the author name for a commit, we may end up either pointing to const storage from getenv("GIT_AUTHOR_*"), or to newly allocated storage based on an existing commit or the --author option. Using const pointers to getenv's return has two problems: 1. It is not guaranteed that the return value from getenv remains valid across multiple calls. 2. We do not know whether to free the values at the end, so we just leak them. We can solve both by duplicating the string returned by getenv().

Rather than parsing the header manually to find the "author" field, and then parsing its sub-parts, let's use find_commit_header and split_ident_line. This is shorter and easier to read, and should do a more careful parsing job. For example, the current parser could find the end-of-email right-bracket across a newline (for a malformed commit), and calculate a bogus gigantic length for the date (by using "eol - rb"). As a bonus, this also plugs a memory leak when we pull the date field from an existing commit (we still leak the name and email buffers, which will be fixed in a later commit).

Many of the date functions write into fixed-size buffers. This is a minor pain, as we have to take special precautions, and frequently end up copying the result into a strbuf or heap-allocated buffer anyway (for which we sometimes use strcpy!). Let's instead teach parse_date, datestamp, etc to write to a strbuf. The obvious downside is that we might need to perform a heap allocation where we otherwise would not need to. However, it turns out that the only two new allocations required are: 1. In test-date.c, where we don't care about efficiency. 2. In determine_author_info, which is not performance critical (and where the use of a strbuf will help later refactoring).

The skip_prefix() function returns a pointer to the content past the prefix, or NULL if the prefix was not found. While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched. This lets you write: if (skip_prefix(arg, "foo ", &arg)) do_foo(arg); else if (skip_prefix(arg, "bar ", &arg)) do_bar(arg); Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>
